JAVA WRAPPER SERVICE DESCRIPTION
The Java Service Wrapper makes very easy to install a Java Application as a
daemon process on Unix systems. The Wrapper monitors a JVM (Java Virtual
Machine) process and automatically restarts it if it that the JVM has crashed
or hung. This process takes just a few seconds once the Wrapper has decided
there is a problem. It also gives the ability to handle process priority.
